论文摘要
讨论了六边形PNICTIDE超导体SRPTAS的配对对称性，并考虑到其多体结构。从Muon-Spin-Relaxation实验观察到的自发性磁化中，预计具有时间 - 反转对称性破坏的拓扑性手性$ D $波状状态。我们在本文中指出，最近有关核旋转局势放松率的实验报告$ t_1^{ - 1} $和超氟密度$ n_s（t）$，似乎支持传统的$ s $ - 波配对，也与手势$ d $ -D $ -Wave State保持一致。差距和多型结构的兼容性在这一论点中至关重要。 We propose that the measurement of the bulk quasiparticle density of states would be useful for the distinction between two pairing states.
The pairing symmetry of the hexagonal pnictide superconductor SrPtAs is discussed with taking into account its multiband structure. The topological chiral $d$-wave state with time-reversal-symmetry breaking has been anticipated from the spontaneous magnetization observed by the muon-spin-relaxation experiment. We point out in this paper that the recent experimental reports on the nuclear-spin-lattice relaxation rate $T_1^{-1}$ and superfluid density $n_s(T)$, which seemingly support the conventional $s$-wave pairing, are also consistent with the chiral $d$-wave state. The compatibility of the gap and multiband structures is crucial in this argument. We propose that the measurement of the bulk quasiparticle density of states would be useful for the distinction between two pairing states.
